I would expect start() to be called when the broker starts (hence the name) not when a client connects. If you really want to debug that method, there is an option you can set on the debug port that prevents the application from running until a debugger attaches. You can find nore details via Google.
I'd recommend figuring out what part of the code you think the problem is in, and set the breakpoint there. Don't try to step through the entire codebase looking for the problem; it'll take too long. And be forewarned that pausing some of the code becomes a race against time because there are timeouts on some code paths, and if you take too long it'll time out and the behavior may change.

For this particular situation we are running version 5.5.1 of ActiveMQ. I downloaded the source code for version 5.5.1 of ActiveMQ and imported it into an Eclipse project I created for this purpose. I then created a remote debugging configuration. I set a breakpoint on the first line of code in the start() function of ActiveMQConnection. I then start my message broker, start my Eclipse debug configuration and then start a JMS client app (i.e. message consumer). I can see from the messages I display in my client (consumer) app that it makes a connection to the message broker, but the breakpoint is never hit in my Eclipse debug session. I selected the start() function because it was the function I was most sure would be called by simply connecting to the message broker from a client. Is there something I’m doing wrong to try to walk through the message broker code? Should I be setting breakpoints in different classes? As an additional piece of information for anyone who decides to help with this I am attaching a screen shot of my Eclipse debugger taken well after my JMS client has connected to the message broker. As you will see, the tab in Eclipse that usually displays the source code is empty. Thanks in advance for helping with this.
